This is great information.
Millions of of jws alive right now and still in their prime have witnessed the failure of the 1914 generation prophecy and its subsequent change.
Despite spending countless hours representing Jehovah, and preaching something as truth to disinterested householders, they have no problem changing the information to whatever the gb tells them to.
They are conditioned to respond to whatever the gb says with subservient obedience.
Jws were delusional in the 70s and still are today.
